Network Security

We have been engaged in business for some time, and have been very successful, however we need to re-examine our network configuration and infrastructure and identify that our network defenses are still reliable, before we make any changes. We need to take a hard look at our current configuration of host, services and our protocols within our organization. Data from a large number of penetration tests in recent years show most corporate networks share common vulnerabilities. Many of these

Networking is part of our everyday lives now. Weather is us using our phones, computer, using GPS for directions, watching 3D movies and TV’s or in our work environments. Network Security has become search a big issue since our day to day live started to be more involve with us. These problems involve in all type of shapes and forms where some of these issues are cyber attacks, physical attacks, or abuse of policies. People are really exposed due to the amount of internet activities we have going on in most of our networks. There are two fundamentally different when it comes to networking, the data networks and the synchronous network comprised of switches. With that being said there are also

In this modern day and age of computing, networks are a huge part of IT. It is important now more than ever that data sent over any network, whether it be a LAN (Local Area Network) or WAN (Wide Area Network; The Internet) is kept safe, private (when required) and uninterrupted in

The system should also allow users to access the network from anywhere as long as they can verify authenticity. The system should also be able to prevent brute force attacks. The system should also make it possible for admins to see suspicious activity. Overall the components in the system should work as intended, to ensure top notch reliability and availability.

There are multiple aspects of security in this network, which I have tried to implement as much as possible. This is where the CIA triangle comes into play, confidentiality, rules and limits to access information; Integrity, making sure the data is accurate and trustworthy; Availability, having reliable access to the information. I am going to talk about each aspect in a list format and explain how it’s used in my network. One thing that will be performed on all network devices is system updates and patches. They will happen on a monthly basis, on a weekend when the networks are not being used.

The best network design to ensure the security of Corporation Techs internal access while retaining public Web site availability consists of several layers of defense in order to protect the corporation’s data and provide accessibility to employees and the public.

Security is almost certainly the most difficult aspect of a network to perfect. It is important to have the correct procedures and components in place to make certain network security is being accounted for and addressed on any given network. The journal, “Future Generation Computer Systems” elaborates on this necessity for an information system. “Future Generation Computer Systems”, this component of a network is discussed thoroughly. “Essentially securing an Information System (IS), involves identifying unique threats and challenges which need to be addressed by implementing the appropriate countermeasures” (Dimitrios Zissis, Dimitrios Lekkas, 2012). This was achieved through configuring access lists as well as CHAP configuration on the routers connecting to the edge

5. What are the three primary methods for implementing security on this network, as well as the advantages and disadvantages each?

Undoubtedly, this paper will generate network information, diagrams, and/or tables; accordingly, these are all included in the Appendix section of the paper. Moreover, the training, vulnerability assessment, and SAQ results are also included as an Appendix in the final paper. Finally, fearing disclosure of proprietary information that could compromise network security, all project data are scrubbed and sanitized to remove sensitive information.

Firewalls are set up on computers to help protect computers and other devices from attacks from potentially harmful websites and other resources. Proxies are servers that act as a middle man for computers. They allow users to make indirect connections to other servers. The LAN-to-WAN domain is where the infrastructure connects to the Internet. Updates, firewalls and proxies will help to keep things running and help to keep it protected.

6. Describe (in plain English) at least one type of ruleset you would want to add to a high level security network and why?

Miller Inc. which is in the business of providing data collection and analytics services relies majorly on network security to keep its competitive advantage. This is because the customers that rely on the company's system trust that since there are sufficient security measures that have been ensured, they can store their data securely. Each of the functional models of the system should have sufficient security measures to ensure that complete security of the whole system architecture is achieved. The three functional modules are the backend module, services or operation module and customer access module. The major relationship between infrastructure and security comes in the role they play to ensure that the end user gets the data that they need when they need it and in the best way possible. Therefore for the three modules, there is a need to balance security with the right infrastructure.

Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.

1. How can a security framework assist in the design and implementation of a security infrastructure?

The network server at focus in this study is one utilized primarily for data storage and internal application sharing as well as for securing numerous desktop computers connected to the network. This work will describe access control that would be put in place for each of these with explanations on why these would be used. A message of at least 20 characters will be generated using a Vigener cipher keys that is at least three letters long, The message will be encrypted along with an explanation of how secure this message is and why. The form of security chose for the network will be identified with physical and electronic security considered. Included will be virus checks, firewalls, and encryption protocols as well as any access protocols explaining how each secures the network. This work will additionally list three specific project goals which if met would reduce or alleviate any problems or deficiencies.
